Thanks DJ for giving us your take. With RGA and now DJ I no longer feel like the lone standard bearer for single ended triodes.

LeRoy,

My full range primary system is a simple-to-build DIY consisting of open baffle 8" Tang Band W8-1808 with super tweeter over Eminence Alpha-15A H-frame open baffles. The top portion ( Tang Bands ) and super tweeter are powered by 2a3 Bottlehead Paramour mono-blocks ( 3.5 wpc ) SET via a Bottlehead Foreplay III preamp while the 15 inch bass Alphas are driven by solid state Dayton mono-blocks ( 150 wpc with built in XO controls ). For bass only, SS rules.

My secondary bi-amped full range system uses a Dared 2a3c integrated SET to drive Tekton/Fostex 4.5" single driver box speakers and a JVC digital AVR to power two DIY open baffle 15" Alphas bass augmentors.

My bedroom 5.1 full range single driver system conists of four DIY Fostex based Frugal Horn Mk3 ( back loaded horns ) with a DIY Fostex center bass reflex design and Velodyne sub powered by a Pansonic XR55 digital AVR.

My garage full range system ( no where to put it in the house ) uses a Miniwatt SET ( 2.5 wpc ) to drive DIY open baffle 8" Betsy's and a Fostex made super tweeter while a Denon AVR drives the open baffle bass Alphas.


The efficiency rating of all main full range drivers is around 94dbs which allows the flea power SET's to drive them with ease. There are no power/sound robbing passive crossovers in these systems and all mains run wide open.
